Application filed May 20, 1916.

To all whom it may concern:

Be it knownthat I, PETER P. CALLAGHAN, a citizen of the United States, residing at Lincoln, in the county of Placer, State of California, have invented certain new and useful Improvements in Chairs; and I do declare the following to be a full, clear, and exact description of the same, reference being had to .the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in chairs, the objectof the invention being to produce a chair of new and novel construction which will be so arranged that it will be especially adapted to conformto the body of any person sitting therein and allow suc person to sit. .in. the most comfortable and non-oppressive position. This I aim to accomplish by building the chair primarily in the same position as is assumed by the' now commonly used chair when the same is tilted backwardly upon its rear legs as is now a very common practice. I provide the same position as though the chair was tilted and yet at the same time have it so constructed that it will at all times be seated firmly on its four legs and in such a manner that it cannot be readily tilted backward. I also aim to constructthe back of the chair so that it will conform directly to the shoulders and back of the person seated in the chair and provide a means for the relief of the spinal column so that the same will not rest directly against the hard back of the chair.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective I for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of my improved chair. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation thereof.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the seat of the chair which in my improved construction is in- "clined at approximately the same angle that the seat of the now commonly used chair Specification of Letters Patent.

would assume if the chair were tilted backward by the person sitting therein. The front legs 2 are connected with the forward end of the seat 1 and extend substantiallyat right an les thereto which brings the lower ends *Fhereof outside of the plane of the front edge of the seat 1. The rear legs 3 of the chair are shorter than the front legs 2' due to the inclination of the seat 1 and rest squarely on the floor but extend rearwardly beyond the plane of the rear edge of the seat 1. This peculiar position of the legs 2 and 3 is such as to hold the inclined seat 1 in such position that when the person is seated thereon and leans against the back of the chair, the weight is so distributed that there is no tendency of the chair to tip backward.

The back of the chair consists primarily of the side posts awhi'ch extend substantially at right angles to the seat 1 which throws them into an inclining position with respect to the floor on which the chair may be seated and thus allows the person seated in the chair to sit in a reclining position. The back 5 of the chair is secured to the posts 4: in any suitable manner and at the upper end thereof curves outwardly as at a to conform to and form a rest for the shoulders of the person sitting in the chair, such back 5 then gradually sloping forwardly toward the chair from its upper to its lower end, the center of the back 5 being provided with a slot 6 to receive the spinal column of the person seated in the chair, such slot being contracted at its center and flaring outwardly at its ends to more readily receive and conform to the spinal column and the muscles radiating therefrom.

As will be readily apparent, the person sitting in my improved chair will have the same easy reclining position as he would have in the now commonly used chair when tilted backwardly upon its rear legs and at the same time the chair will be firmly set and resting upon all four ofits legs. This avoids the chance of breaking the chair, overcomes the chance of the chair tipping over backward and at the same time effects a very easy sitting posture for the person in the chair. The back being constructed as it is fits the back of the person in the chair to a nicety and the slot 6 prevents any pressure against the spinal column. From all of this it will be apparent that I provide a comfortable chair for sitting purposes and one in which the injurious pressure to the spinal column and the back of the neck is entirely overcome.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the object of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure 'by Letters Patent is:

l. A chair comprising a seat normally set at an inclination to the horizon and slop ing from its front to its rear edge, front and rear legs on the chair, the lower ends of the legs being in the same plane, a back on the chair, such back comprising side posts and a filler portion between the posts, such filler portion curving rearwardly at its upper end and gradually extending toward the chair from its upper to its lower end, such filler portion being provided with a central slot, such slot being contracted at its center and flaring outwardly at its ends.

2. A chair comprising a seat normally set at an inclination to the horizon and sloping from its front to its rear edge, front and rear legs on the chair, the lower ends of the legs being in the same plane, a back on the chair, such back comprising side posts and a filler portion between the posts, such filler portion curving rearwardly at its upper end and gradually extending toward the chair from its upper to its lower end.

3. A chair comprising a seat normally set at an inclination to the horizon and sloping from its front to its rear edge, front and rear legs on the chair, the lower ends of the legs being in the same plane, a back on the chair, such back comprising side posts and a filler portion between the posts, such filler portion curving rearwardly at its upper end and gradually extending toward the chair from its upper to its lower end, such filler portion being provided with a central slot.

In testimony whereof I affix my signature.

PETER P. CALLAGHAN.
